Matter enclosed reissue specification;

This invention relates to registration devices for gas meters, and has to do with registration devices which may be placed remote from the meter and will indicate accurately the amount or volume of gas which has passed through the meter during any given time.

It is the common practice for meter readers to visit residences and other establishments periodically for reading the gas meters to determine the amount of gas which has been supplied to the resident or user. Gas meters commonly are positioned in the basements of houses and like establishments or in other suitable places indoors, and it frequently happens that the reader when calling to read the meter cannot obtain access thereto due to absence of the resident, or other causes. The objections to that are obvious. With a view to avoiding that condition, various proposals have been made for providing registration or indicating devices exterior of the residence, so as to be at all times accessible to the reader, and operatively con nected to the meter within the residence. Such devices with which I am familiar are, in general, rather complicated and expensive and do not always operate satisfactorily.

My invention is directed to a registration de-' vice of comparatively simple and inexpensive construction, which may be placed exteriorly of the residence, so as to be at all times accessible to the meter reader, and which will operate satisfactorily and in a manner to indicate accurately the amount or volume of gas which has passed through the associated meter during the period since the last reading device of my invention may be applied to gas meters of known type without necessitating any material change in the meter itself. In its broader aspects, my invention comprises a chamber having a movable wall and subject to the gas pressure within the meter, means actuated by the measuring mechanism of the meter for moving the movable wall of the chamber in one direction and means for moving the movable wall in the other direction, in conjunction with a second chamber exterior of the meter and hav ing a movable wall operatively connected to a counting or registration mechanism, this second chamber being connected to the first chamber so as to cause actuation of the registration or counting mechanism responsive to movements of the movable wall of the latter chamber. While my invention, in the preferred form thereof shown, is particularly suitable for use with meters for fuel gas, it'is also applicable, in its broader thereof. The registration uary 2, 1951.

I have shown the registration device of my invention as used with a gas meter 5 of known type. This gas meter 5 is a Glover type of meter and is provided with measuring mechanism enclosed within a box like casing 6. The measuring mechanism comprises bellows (not shown), flag rods I actuated by the bellows, flag arms 8 on the upper ends of rods 1, and an index shaft 9 on which is secured a gear 10 driven by a worm i l which is rotated in a known manner by known operating connections to short flag arms 12 hinged to the long flag arms 8. The casing B is provided interiorly with a horizontal partition or valve table I3 defining with the portion of casing 6 extending thereabove a space commonly termed the gallery chamber. The flag arms 8 and I2 and associated mechanism just described are disposed above valve table [3 in the gallery chamber. Inlet and outlet tubes l4 and I5, respectively, are disposed at opposite sides of casing 6, and an inlet channel l6 extends from tube [4 inwardly along the underface of valve table 13 to suitable valve means (not shown), actuated by the mechanism which drives worm II, for admitting gas to and exhausting gas from the two bellows alternately. The gas exhausted through the valve means leaves the meter through the outlet tube 15. The gallery chamber is kept filled with gas at meter operating pressure, for a purpose to be explained presently. Normally, leakage of gas through the stufiing box of the tangent arm shaft of the operating connections between the worm ll and the flag arms 8 and i2 may be relied upon for maintaining the gallery chamber filled with gas ,sr AVAILABLE COP.-

at meter operating pressure, or substantially so. Preferably, however, I provide a small opening 18 through valve table l3 into the inlet channel It, for that purpose. In some meters of the newer types the meter valves are not partitioned off from the gallery chamber or space above the bellows chamber, and in such meters the space in the upper portion of casing 6 is in direct communication with the gas inlet so as to be maintain-ed filled with gas under inlet or meter operating pressure. Accordingly, in such meters, there is no necessity for providing the opening l8, nor for relying upon leakage of gas to maintain the pressure within the chamber or space within. which the registration device of my invention is, in part, disposed. As will be understood from what has been said, the meter is of known construc'tion and operation and need not be further described in detail.

The registration device of my invention comprises a cylinder 23 provided with base flanges 2| seating upon a base plate 22 and secured thereto in a suitable manner, conveniently by means of screws 23 wh ch pass through base plate 22 and serve also to secure the latter to valve table 13, upon the upper face of which base plate 22 seats. A table 24 is supported above the inner portion of base plate 22, by posts 25, and receives a rotatably mounted vertical shaft 26 fitting through a corresponding opening in plate 2% and having at its lower end a stepped bearing in base plate 22. A worm gear 27 is secured on shaft 26 and meshes with. a worm 28 secured on the index shaft 3. In the opera tion of the meter 5, the worm gear 27 is rotated counterclockwise, as viewed in Figure l, at low speed. 1

Two oppositely directed abutment members or pins 30, preferably of approximately semi-cylindrical cross section, as shown more clearly in Figure 1, are secured to the worm gear 21 at diametrically opposite points thereof and extend downward therefrom with their ends in proximity to the table 24. The pins 30 are disposed to contact head 32 at the outer end of a piston rod 4* 33 slidable through boss 34 of a cylinder head 35 suitably secured on the inner end of cylinder 20, conveniently by bein screwed thereon. A piston 36 (Figure 1), preferably of cupped form with its flange directed toward the inner cylinder head 35, operates in cylinder 2:] with a close fit therein effective to prevent leakage of gas aboutpiston 36 from the inner portion of cylinder 20 but not presenting appreciable frictional resistance to movement of piston 35 within cylinder 23. The inner cylinder head 35 is provided with one or more openings,- one of which is shown at 38 in Figure 2, establishing free communication between the inner end of cylinder 23 and the gallery chamber or spaced within which that t cylinder is disposed, for a purpose which will appear more fully presently.

The outer end of cylinder 20 is closed by a head 40 conveniently formed integral therewith. This head 40 is provided with an inlet port 41 disposed coaxially of cylinder 26 and normally closed by an outwardly opening and inwardly closing valve 42 having a stem 43 projecting inwardly of cylinder 29 a short distance beyond head 40. The valve 42 is urged in closing direction, and northe arms 20, the inner end of piston rod 33,

which projects a short distance inward beyond piston 36, contacts valve stem 43 and moves the valve 4 2 outward into open position, in opposition to the compression spring 44-, for a purpose to be explained more fully later. In that connection, it will be noted that the port 4! in head 40 is of appreciably greater diameter than the valve stem 43, so that upon opening of valve 42 communication is established between the outer end of cylinder 29 and the gallery chamber or space within which that cylinder is disposed.

A spirally wound compression spring i? is suitably mounted on the inner face of the outer cylinder head 40 and extends therefrom toward piston 36 a substantial distance beyond stem 43 of the valve 42. A tubular fitting 48, of

known type, is mounted in cylinder head 40 and opens into the outer end of cylinder 20. A conduit 49, conveniently a length of copper tubing of appropriate diameter, is secured at one end in fitting 48 and opens therethrough into the cylinder 20. The tube 49 passes through the adjacent side wall of meter casing 5, by means of a fitting 53 of known type which provides a as tight seal with the wall of casing G and about the conduit or tube 49. The tube 49 passes through a wall 52, which may be the foundation wall of a house or dwelling, it bein assumed for purposes of description that the meter 5 is: disposed adjacent the inner face of wall 52 within the basement of dwelling. The outer end of, tube 49-is secured in a fitting 53, of known type..- mounted in a recessed base 54 of a chamber 55 suitably mounted, as by brackets 55, on wall 52 at the outer face thereof. Fitting 53 opens into the recess of base 54 through a passage 51 therein. A flexible diaphragm. 58- extends across the outer side of base 54, to which it is suitablyse cured, conveniently by a clamping ring 59. The base 54 and the diaphragm thus provide a chamher having a movable wall defined by the dia phragm 58, this chamber being in communication through the tube 49 with the outer end of cylinder 20. A counter 60, which may be a cycloineter counter of known type, is disposed outwardly beyond diaphragm 53. Conveniently, counter 60 is mounted on bosses 6| on the clamp ring 53. Counter 60 is operated by means of an arm 62 clamped on shaft 63 thereof, movement 0 m.

62 in clockwise direction, asviewed in Figure 1, being efiective for advancing the counter one: space and movement of arm 62 in counter-clock wise direction being ineflective for operating the counter, as is known. Arm 62 is adiustably con- 65 to diaphragm 58 centrally nected, by a rod thereof. The counter and associated parts are enclosed by a cup shaped cover 66 fitting about ring 59 and secured to base 54 in a suitable manner. Preferably, screw studs 67, secured in base 54 extend through bosses 68 18 being threaded onto studs t7 and seating against bosses 68, there being a seal wire H inserted through studs 67 with its ends secured together by a lead seal 72. The cover 66 is provided, at the front thereof, with an opening 14 closed at its inner side by a glass plate or panel 15, providing a window through which the numbers on the discs of the cyclometer counter may readily be viewed.

The diaphragm chamber structure shown in the modification of Figure 4 is the same as that; Figure 1, except that the rod 65 iswith a rearward extension 65a of re-.

of cover 63, nuts:

hrs boss '18-projecting from base 54a of the diaphragm chamber. A compression spring is disposed about extension 65a of rod 65 and is confined between boss 13 and the inner one of two nuts 8| threaded on rod 65 for clamping the central area of diaphragm 58 between two an-' nular plates 82. The cover 66 is provided with a port 83 which permits free entry of atmospheric air, for a purpose to be explained presently.

In the operation of the meter 5, the worm wheel 21 is rotated slowly in counterclockwise direction, as view in Figure 1, turning through one complete rotation for each two hundred cubic feet, for example, of gas passing through the meter, it being assumed that the indicator or counter 66 is to be actuated once for each one hundred cubic feet of gas passing through the meter. During turning of the worm wheel 21 through one-half rotation, one of the pins 30 thereof contacts head 32- of piston rod 33 and moves the latter, and with its piston 36, inwardly of cylinder 26 toward head thereof. During such inward movement of the piston 36, the gas enters the inner end of cylinder through opening 38 so as to avoid production of a partial vacuum such as would interfere with free inward movement of piston 36. As will be understood from what has been said, the piston 36 movesinwardly of cylinder 26 quite slowly. In the continued movement of piston 36 toward cylinder head 40, it contacts the inner end of compression spring 41 and places the latter under compression. As piston 36 approaches cylinder head 40, the inner end of piston rod 33 contacts valve stem 43 and moves it outward, thus opening the valve 42. Opening of valve 42 admits gas under inlet 01- meter pressure tothe outer end of cylinder 29 and thence through fitting 48 and tube 49 to the diaphragm chamber 55. The gas entering chamber forces the moveable wall .or diaphragm 58 thereof outward, thus turning arm 62 and shaft 63 oi the counter 60 in counterclockwise direction, as viewed in Figures 1 and 4, ineffective for operating the counter 68, as above noted. In the continued rotationof worm gear 21 pin 30 thereof passes out of contact with head 32 of piston rod 33, releasing the .latter and the piston 36 for outward movement. When that occurs, the com: pression spring 4'I moves the piston 36 rapidly outward in cylinder 20, toward head 35 thereof.

In the first part of this outward movement of piston 36, valve 42 closes under the infiuenceof its associated compression spring 44, and in the continued outward movement of piston 36 gas is withdrawn through tube 49 from the chamber 55.

That creates a partial vacuum within chamber 55 and the moveable wall or diaphragm 58 thereof is then forced inward by atmospheric pressure, thus swinging arm 62 and shaft 63 of counter 60 in clockwise direction, as viewed in Figures 1 and 4, effective for advancing the counter one, space. In"that manner, the counter 60 is advanced one space for each one hundred cubic feet, for example, of gas passing through the meter 5.

The inward movement of the piston 36 is quite slow, as above noted, depending upon the amount of gas passing through the meter, and may require several days. During such inward move ment of the piston 36 slow'leakage of gas about the piston may occur from between the latter and cylinder head 40, such that no effective pressure is created in the chamber 55, such as would move the moveable wall'or diaphragm 58 thereof outwardly to an appreciable extent; Under certain conditionaas where large volumes of gas pass through the meter in comparatively short time periods and substantial leakage about the piston 36 does not occur, the movement of piston 36 inward of cylinder 20 toward head 48 thereof may create sufilcient pressure within the. diaphragm chamber 55 to cause outward move-- ment of diaphragm 58. Such outward movement of the diaphragm would not, however, affect the accuracy of operation of the counter 68 which, as noted, is advanced one space only when the diaphragm 58 moves inward of chamber 55. Assuming the diaphragm 58 to have been moved outward during the inward movement of piston 36 toward cylinder head 40, the rapid outward movement of piston 36 under the influence of compression spring 41, from its innermost position would be effective to produce a partial vacuum within the diaphragm chamber 55, so as to cause inward movement of diaphragm 56 and actuation of the counter 66 in the manner above described.

In certain cases, where the inlet or meter pressure of the gas is exceptionally low, the compression spring of the modification shown in Fig- 5 ure 4 supplements the pressure of the gas entering the diaphragm chamber 55, to assure that the diaphragm 58 will be moved outward sufficiently to assure proper operation of the counter upon inward movement of the diaphragm 53 under atmospheric pressure. Accordingly, where conditions of low gas pressure are apt to be en countered, I preferably provide the compression spring 86, as and for the purpose stated. As will be understood from what has been said the compression spring 80 is rather light and exerts. outward pressure on diaphragm 58 less than the inward atmospheric pressure exerted thereon. In cases where the entering or inlet gas pressure is adequateto assure full outward movement of diaphragm 58, the compression spring Bll .may be- Omitted. I As above indicated, and as will be understood, changes in detail may be resorted to without departing from the field and scope of my invention, and I intend to include all such variations, as fall within the appended claims, in this application in which the preferred forms only of. my invention have been disclosed.
